AUBURN, Ala. -- An injured Sean White came off the bench to throw a touchdown pass and Josh Holsey intercepted a last-minute throw to lift No. 9 Auburn to a come-from-behind, 23-16 win Saturday over Vanderbilt.

The Tigers (7-2, 5-1 Southeastern Conference, No. 11 AP) sputtered after starting John Franklin III in place of White, who had an unspecified injury. White returned to open the second half with Auburn down 13-10, then threw a 21-yard touchdown pass to Darius Slayton and led two field goal drives.

Auburn coach Gus Malzahn said White was "banged up" and didn't take a snap in practice leading up to the game.

"Sean threw some in warmups, moved around, and it was kind of one of those deals he thought he could go," Malzahn said. "And at halftime we just made the move. He was ready to go, and obviously he gave our offense a spark."

The win coupled with Mississippi State's upset of No. 7 Texas A&M means Auburn can win the SEC West with victories over Georgia and No. 1 Alabama. That game was airing on Auburn's huge video board in the minutes after this one ended, setting off another celebration for fans after the Tigers' sixth straight win.

Vandy (4-5, 1-4) stayed alive into the final minute against the 26-point favorites thanks to Caleb Scott's 29-yard catch of a tipped ball on fourth and 18. The Commodores moved to Auburn's 30 before Holsey's interception put it away.

"I saw my guy go to the flats and I saw (quarterback Kyle Shurmur) pat the ball one too many times, and I just felt something was going to be behind me," said Holsey , whose pick set up the final touchdown against Mississippi. "My instincts took me to the ball."

The drive was set up when Daniel Carlson's attempt at his fourth field goal was blocked. Alabama native Zach Cunningham leapt over the line at the snap and knocked it down.

White completed 10 of 13 passes for 106 yards and Kamryn Pettway topped 160 rushing yards for the fourth straight game. Pettway ran 25 times for 173 yards, but came up limping at the end of a 60-yard run to set up the decisive score after appearing on his way to the end zone. He was clutching his left leg on the ground.

Shurmur completed 24 of 36 passes for 221 yards and a touchdown. He also had a 21-yarder on the final drive before the pick.

THE TAKEAWAYAuburn: The Tigers showed they can survive a down-to-the-wire game and imperfect performance, but perhaps not an SEC game without White. They still looked vulnerable to the pass after Mississippi's Chad Kelly's school-record performance. Auburn was especially thin at linebacker with Deshaun Davis's first half ejection for targeting. Starter Tre' Williams was out with an injury.

Vanderbilt: The Commodores were one big play from winning a third straight game for the first time since 2013. They couldn't get the running game going; the SEC's No. 2 rusher Ralph Webb gained 46 yards on 13 carries.

POLL IMPLICATIONSAuburn didn't earn style points for the win, but still could move into the Top 10 and possibly move up a spot or two in the playoff rankings.
